I am trying to decide between the two. I mainly use it for desktop and occasional travel, vaca, etc. I have a 3 1/2 year old 2.16 cd2 now and my heavy work is on photoshop, weddings etc. I also use it with a 30" cinema so it will not be my photo editing monitor. However the hi res 17 does seem to have a few more things going for and the price difference is not that much. On the other hand is the larger laptop that important.. duhh. any ideas?
